Rotary bearing is a kind of large bearing which can bear comprehensive load, and can bear large axial, radial load and overturning moment at the same time. Slewing bearings are generally equipped with mounting holes, internal or external gears, lubricating oil holes and sealing devices, thus making the design of the main engine compact, easy to guide and easy to maintain.

Rotary bearing in the real industrial application is very extensive, known as: "machine joints", its main applications are widely used in: crane, rail crane, port cranes, deck cranes, metallurgical cranes, container cranes, excavators, filling machine, and CT machine standing wave therapy apparatus, navigation, radar antenna tower, missile launcher, tanks and robots, and revolving restaurant, etc.
